Fourth, use: heavy calcium carbonate can be divided into ordinary and heavy calcium carbonate superfine heavy calcium carbonate. Heavy calcium carbonate is commonly used as a filler, is also widely used man-made floor tiles, rubber, plastics, paper, coatings, paints, inks, cables, building supplies, food, medicine, textiles, feed, toothpaste and other household chemical industries carbonate Sales of calcium, as calcium carbonate filler played reaction volume increase of products, reduce production costs. Powder characteristics of a heavy calcium carbonate particles of irregular shape, is more dispersed powders. b broad particle size distribution. c large particle size, the average particle size is usually 5-10μm. To determine the average particle size heavy calcium carbonate processing of calcium carbonate, to be measured, such as particle size distribution function and the settling velocity or surface area than the powder phenomenon like functions. As a simple method is to measure the electron microscope photograph of the particle projected length and width calculate the geometric mean particle diameter as the apparent diameter, and then take the median diameter as the average particle size. d calcium carbonate of average particle size is taken as the average particle diameter of the front surface-modified precipitated calcium carbonate or calcium carbonate.
